Part 8/13:
Assembly and Testing: When designing the system, rigorous testing of hardware (or data infrastructure) is crucial. Ensuring machines and tools are within specifications.
Input Data Monitoring: Before processing, verify the raw input data. Are the files coming from vendors complete and correct? Is the raw data healthy enough for processing?
Output Monitoring and Sampling: Post-processing, conduct sampling, observability checks, and pattern analysis to ensure the final data product aligns with expectations. This phase often receives the most attention but should be complemented with earlier safeguards.
